SPECIFICATION forming part of Letters Patent No. 593,062, dated November 2, 1897.

Application filed August 17, 1896.

T0 ctZZ whom it may concern:

Be it known that I, RICHARD THEW, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Handling Coal, Ore, dzc. and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for handling coal, ore, and other material on docks, in railway yards, and other places.

The invention is, in a sense, an improvement in the class of machines shown and described in certain prior patents granted to me-to wit, No. 436,928, dated September 23, 1890, and No. a,082,dated January 14:, 1896- since it, like them, includes a movable trolley, a sweep-arm pivoted thereto, a bucket, scoop, or shovel carried by said arm, and mechanism for operating said sweep-arm and trolley. The machine hereinafter described embody-- ing my invention is, however, a traction-machine, having power to propel itself from place to place independently of any tracks or g'uideways, and the invention in part resides in the mechanism for effecting this result.

Other parts of the invention relate to other parts of the machine and are not necessarily confined in their use to such a traction-machine; and the invention consists in the construction and combination of parts, as hereina'fter described, all of which is pointed out definitely in the claims.

In the drawings, Figure 1 is a perspective view of a machine embodying my invention. Fig. 2 is a bottom plan view of the traction mechanism. Fig. 3 is a sectional front view on line 3 3 of Fig. 4 is a sectional side view of the fifth-wheel mechanism. Fig. 5 is front view of the trolley and its supports; and Fig. 6 is a side view, partly in section, of the mechanism for moving the trolley.

Referring to the parts by letters, A represents the truck, which may be of any suitable construction. As shown, this truck consists of two flanged beams a a, forming the sides, a cast frame a, which lies between and Serial No. 603,071. (No model.)

is bolted to the said beams, and one or more transverse beams a. and supported by the truck is a circular casting F, having an annular channel f in its top surface and a circular rack f on its periphery. The truck is supported on wheels 0 O C C The rear wheels O O are independently mounted on an axle c, which is secured to the truck-beams a a by means of brackets 0 The front wheels C O are mounted on an axle c which-is connected with the truck by any suitable fifth-wheel contrivance-as, for example, that shown in Fig. 2, in which E represents a king-bolt which is mounted in hearings in the brackets (t a, which are secured to the front end of the truck. The king-bolt has a yoke 6 near its middle, through which the front axle passes and to which it is pivoted on a pin 6.

A base 13 supports the motor and other mechanism driven thereby, which I will presently explain. This base may consist of two side flanged beams b b, suitably connected together, and a casting b, lying between said beams and bolted or otherwise secured there to. This casting has on its under side an annular groove 19 of the same diameter as the similar groove f, and the entire base is supported on a row of balls H, which run in the raceway formed by the two annular grooves Z2 and f.

A vertical sleeve I passes through the platform-casting b and the truck-casting a at the center of the annular grooves f and b and this sleeve is bolted to the truck-casting a. This sleeve serves as the pivot of the base 13, and it also furnishes a bearing for the hollow shaft J which passes through it and serves as the means for transmitting power from the mechanism on the base to the mechanism suspended from the truck. This shaft J may have the gear j secured to its upper end, whereby the shaft may be revolved by a suitable motor on the base.

A motor of some sort is mounted upon the base B, and suitableintermediatemechanism for connecting the motor to the several shafts, which are shown and described, must be provided, but no attempt has been made to show in detail the motor or such connecting mechanism.

Mounted in suitable bearings on the base Secured by bolts upon and extending from the upper to the lower side thereof is a shaft K,having on its lower end a pinion k, which engages with the rack f. As the shaft K is turned by the motor and connecting mechanism the base B is revolved about its axis'upon the balls H.

Mounted in brackets d d on the under side of the truck is a shaft D, and a bevel-gear cl, which is fixed to said shaft D, meshes with a bevel-gear 7' on the lower end of shaft J; A gear (1 is also secured to said shaft D, and it meshes with a gear G, the hub of which enibraces and is loosely mounted upon the adjacent ends of the two shafts M and M. These shafts are mounted in brackets m m which are secured to the under side of the v truck.

Two bevel-gears gg are mounted on the gear G on radial axes, and said gears project fromboth sides of said gear G. The bevelgears m m, which are keyed, respectively, to the shafts M M, mesh with both of these I gears g g on opposite sides of theirown centers. The sprocket-wheels m m are keyed,

respectively,to the two shafts M M. Sprocket- I wheels O are fixed, respectively, to the rear wheels. 0 O, and chains 0. C (indicated by dotted lines in Fig. 2) connect the sprocketwheels 0 C with the sprocket-wheels 771 771 whereby motion from the shafts M M is transmitted to the wheels 0 G. If when the gear G is revolved theresistance to. the roiationof both rear wheels is subs: antially equal,

the bevel-gears, g 9 will not revolve upon their axes, wherefore'both shafts hf M will be revolved equally in the same direction and I so. will both wheels CO; butwhen the resistance to the rotation of said wheels is unequal the gears g Q will be revolved upon their axes in one direction or the other, and consequently the shafts M M will be revolved at unequal speeds. For example, if the wheel 0 is absolutelyprevented from revolv- 7 ing, the shaft M and gear m cannot revolve,

On the top of the platform 13: are secured the two upright side frames T, having cantaliver extensions 25. These side frames are connected by transverse overhead bars t, and they support the rails S on which the trolley R runs. The trolley may have the grooves r in its sides, which receive the rails, whereby it may slide backward and forward upon the rails, or it may be of any other construction wise.

adapted to be moved backward and forward upon the said rails. I I I The sweep-arm P is pivoted to the trolley in the usual or any appropriate manner. On its lower endis a bucket, scoop, or shovel p, which is preferably adapted to automatically 'scoop up the material to be handled. The

sweep-arm is moved by means of the tackle-cable 0, which passes through the pulley-blocks 0 g on the said sweep and on the end of an I inclined overhanging derrick arm Q, respectively. The cable is taken in or paid out by a Winding-drum 0 on the platform, which is operated by suitable connection with the motor.

The trolley is caused to traverse the track I I I 5 backward and forward by means of a screw V, which is secured to the trolley.

mounted on the screw between two fixed shoulders e v prevents it from moving end- This nut hassprocket-teeth 12 upon its 1 outer periphery, and it is driven by a chain Io, which connects it with a sprocket-wheel A nut '0,

'0 on a driven shaft "22 Extending down through the hollow'shaft I J is a shaft X, having a hand wheel m or other means for turning it upon its upper end. On

its lower end is a worm-screw :0 which encured to said shaft. The chains 1/ 3 which I I I are secured to the front axle on opposite sides of the fifthwvheel, are woundin opposite direc- IOO tions upon said drums, respectively. Therefore by turning the shaft X the front axle may be turned so as, to guide the movement of said machine,

The described machine is entirely selfcontained, carryingits own motor. It may move from place to place and into proper relation to the pile of ore, coal, or other material to be. handled. Then by operating the trolley and sweep-arm by means of the described mechanism the material is shoveled up by the scoop. The platform B may then be turned upon its axis, whereby, together with the movement of the trolley and sweep-arm, the scoop or bucket may be carried near any desired point, as a car or hatchway, and dumped.

By the proper operation of the described machine a surface may be cleaned with approximately the same completeness as could be done by men with shovels.
